Abstract

ABSTRACT Making lotion from Virgin Coconut Oil (VCO) and Aloe Vera to which an emulsifier has been added requires antimicrobial ingredients, because the water phase facilitates the growth of microorganisms. The presence of methyl paraben preservative is very important in oil-in-water emulsions, because the shelf life of the product will last longer. This research aims to determine the effect of span 60 on homogeneity properties. The physical properties of the lotion include homogeneity test, pH test, viscosity test and specific gravity test based on SNI-16-3499-1996. The experimental process was carried out with varying weights of span 60 (sorbitan monostearate) 1 mg, 3 mg, 5 mg, 7 mg, methyl paraben with varying weights of 1.5 mg, 2 mg, 2.5 mg, 3 mg and a stirring time of 21 minutes. With the liquid phase and the heated oil phase.0.95- 1.05 g/ml. Keywords: Virgin Coconut Oil (VCO), Aloe Vera, Emulsifier, Span 60 (Sorbitan Monostearate), Methyl Paraben, Homogeneity.

Abstract

CPO (Crude Palm Oil) is the result of processed palm fruit in the form of crude oil so that it needs to be refined so that it can be used by consumers, one of the purification processes of CPO (Crude Palm Oil) is to use the bleaching process. The purpose of this study is to determine the effect of activated carbon size, temperature and bleaching process time on the crude palm oil (CPO) produced. This study used three independent variables, namely the size of activated carbon (120/150, 150/180 and 180/200) mesh and bleaching temperatures of 150oC, 160oC, 170oC and bleaching times of 50 minutes, 60 minutes and 70 minutes. The results showed that the higher the temperature and time in the bleaching process, the lower the level of free fatty acids in CPO both in the size of activated carbon (120/150, 150/180 and 180/200) mesh. In activated carbon, the ash content did not meet the SNI 06-3730-1995 standard while the moisture content met the standard. For CPO (Crude Palm Oil) after the bleaching process, the  best results were obtained at a particle size of 120/150 mesh with a temperature of 170oC and a time of 70 minutes. Keywords: Crude palm oil (CPO), activated carbon, and bleaching
